• Game Technologies: DirectX, XNA, XACT, etc. Issue with far plane distance vs. radius in a camera component

  Hello, I'm curious about the behaviour of my camera class. It is a simple class that controls camera view. It behaves like it should, except when the radius happens to be the maximum value that I've set in code (farPlaneDistance). When the mouse wheel is moved, this changes the near and far plane distance: // don't get too far if (radius < nearPlaneDistance) {      radius = nearPlaneDistance; } // don't get too close if (radius > farPlaneDistance) {      radius = farPlaneDistance; } And I use the radius to update the position vector of the camera: // update position vector position.X = ( float )(radius * Math .Cos(vertical) * Math .Cos(horizontal)); position.Y = ( float )( ...Show All

• SQL Server Unable to retrieve the @@Error code in stored procedure

  Hi All, In my application on click of Delete button, actually I am not deleting the record. I am just updating the flag. But before updating the record I just want to know the dependency of the record ie. if the record I am deleting(internally updating) exists any where in the dependent tables, it should warn the user with message that it is available in the child table, so it can not be deleted. I want to check the dependency dynamically. For that I have written the following procedure. But it is updating in both cases. CREATE proc SProc_DeleteRecord @TableName varchar(50), @DeleteCondition nVarchar(200) As Begin Begin Transaction Declare @DelString nvarchar(4000) set @DelString = 'Delete from ' + @TableName + ' where ' + @DeleteCon ...Show All

• Visual Basic VS 2005 - Reading XML config file

  My solution consists of a Windows Library (that creates a DLL), an EXE that is the Windows Service and a Setup project for deployment. The Windows Service references the DLL project. Everything is installed and deployed. 1. When I run the service, my code needs the current directory of my installed windows service application and library (c:\Program Files\Perf\PerfService in this case) but when I use the following code: path = My .Computer.FileSystem.CurrentDirectory It returns : C:\WINDOWS\SYSTEM32 How do I get where my DLL and EXE are installed 2. I am using a My.Settings config file (app.config) to store application settings for the DLL. How do I include this in my Setup project so that I can manually change settin ...Show All

• Visual Studio 2008 (Pre-release) How does one express a many-to-many 3-table arrangement as an entity model?

  Take this schema: Authors (ID, First Name, Last Name, etc) Books (ID, Title, ISBN, etc) BookAuthors (BookID, AuthorID, IsPrimary) So, this is a representation of your standard "mapping" scenario where you map many rows of one table to many rows of another table via an interim "mapping" table that supplies the many-to-many relationship. In my experience, I encounter this table structure all the time and is considered extremely common and still satisfies 3NF. As a rule, using ADO EF, I should not have to modify my schema to de-normalize to produce a better relational model - the model should be object/relational and the schema should be 3NF - that's the whole point of an abstracted entity model in the first place. So, I w ...Show All

• Visual C# Underline text

  I was wondering if there was any way to underline the text of a string... Application: For right now I am outputing a bunch of strings into a message string to display in a message box. Later I will be outputting to a text file. I have searched the MSDN Lib to no avail; if someone could point me in the right direction, that would be great. Can you use HTML code in VC# Thanks Thom Just one last thing for now: will that operation allow for the fiel to be appended on multilpe runs of the program It sounds like that will just make the stream longer then write to the file, its not appending the file each time it is run it would just overwrite on the next run Is there anything for that Thanks Tom ...Show All

• Windows Live Developer Forums FF Polyline ReArraging?

  I am having very strange behaviour in FF which seems to take the LeftTop edge of the last Poly I add and reArrange all of my other Polys' starting at that LeftTop edge, strangley keeping their proper shape...in certain cases even cropping the regions. Live Example: http://mssa.coba.usf.edu/mapControl/ Use IE to see proper result first, then watch it go nuts in FF.

• Internet Explorer Development Vist or IE7 and Cookies

  I have an application that uses the webbrowser component and when launched goes to a website. Previously I’ve navigated to the web site and set the cookie to remember who I am so I no longer have to log in. However, in my application I am still required to log in. This app worked fine under XP, but not doesn’t appear to work under Vista. Is this due to IE 7 Vista Security issue in both Any help would be appreciated, by me and my wife as I keep kicking her off her machine to run this app :) Thanks Wayne This is most likely a security change caused by Vista Protected Mode.

• Windows Forms Dragging and Dropping an Object

  Hi guys, I'm trying to determine if it is possible to drag and drop an object between two controls. I have a class called AudioTrack which inherits ListViewItem so that it can go straight into a listview. It has strings for the Artist and Title, and a byte array for the track data itself. I have another control (a player) which can load an AudioTrack class and play it. Is it possible to drag the AudioTrack from a ListView onto the control, and have all the data intact I've already got it starting the dragdrop operation, but can't get the player to accept it - I'm getting stuck in the DragDrop event at e.Data.GetData() and don't know what to put as the format.

• SQL Server Comparing millions of records from file A and B

  I'm trying to compare about 28 million records (270 length) from table A and B using the Lookup task as described in this forum. The process works fine with about two million records or so on my desktop ( p.4 3.39GHz, 1.5 GB Ram), but hangs with the amount of data I'm trying to process. I tried using full and partial caching, but to no avail. I'm thinking this is a hardware resource problem. So, does anyone has any recommendation on the hardware needed for this kind of operation and/or suggestion Thanks in advance...
